DETAILED DESCRIPTION OF THE DISCLOSURE
Definitions [0045] By "antagonist" it is intended to mean a receptor ligand that does not provoke a biological response upon binding to a receptor, but which blocks or dampens (decreases, lessens, etc.) agonist-mediated responses. (An "agonist" is a ligand that binds to a receptor and triggers a response, i.e., an agonist produces an action, often mimicking the action of a naturally occurring substance.) Antagonists thus have affinity but little or no efficacy for their cognate receptors, and binding of an antagonist to a receptor will disrupt the interaction and inhibit the function of an agonist or inverse agonist at receptors. Antagonist activity may be reversible or irreversible depending on the longevity of the antagonist-receptor complex, which, in turn, depends on the nature of antagonist receptor binding.
[0046] As used herein, the term "about" or "approximately" can mean within an acceptable error range for the particular value as determined by one of ordinary skill in the art, which will depend in part on how the value is measured or determined, e.g., the limitations of the measurement system. For example, "about" can mean plus or minus 10%, per the practice in the art.
Alternatively, "about" can mean a range of plus or minus 20%, plus or minus 10%, plus or minus 5%, or plus or minus 1% of a given value. Alternatively, particularly with respect to biological systems or processes, the term can mean within an order of magnitude, within 5-fold, or within 2-fold, of a value.

Combinations comprising a central nervous system (CNS) active agent and sequestration agent 100541 The present disclosure is related to a method of use, composition, and kits comprising a combination of a sequestration agent (e.g., a cyclic cucurbituril, an acyclic cucurbituril, a pillararene, a cyclodextrin, a calixarene, or the like) and a CNS active agent.
100551 Single agent use of CNS active agents or sequestration agents to antedate the effects of toxic agents, may not be sufficient. For example, Naloxone has a short half-life (-60 min) and is becoming less effective against newer synthetic opioids that have a longer half-life, such as fentanyl with a half-life of 10-12 hrs. This often results in a secondary overdose phenomenon known as renarcotization. To avoid renarcotization, the standard of care is to administer higher and more frequent doses of naloxone. However, this can lead to a secondary complication called precipitated opioid withdrawal (POW), a serious and sometimes life-threatening condition.
Moreover, the relative binding affinities of some CNS active agents to their receptor may not be sufficient to completely displace the toxic agent.
100561 The present disclosure utilizes a combination of sequestering agents and CNS active agents to displace and clear toxic agents. Without wishing to be bound by any theory of mechanism of action, it is contemplated that the CNS active agent displaces the toxic agent from its receptor (e.g., opiate receptor), and the sequestration agent captures and clears the toxic agent, e.g., from a body of a subject. In some embodiments, the sequestration agent and CNS active agent are co-formulated and/or co-administered, or are administered in close proximity to each other (e.g., less than 5 minutes apart). In some embodiments, the CNS active agent is administered first so as to free the toxic agent from its receptor, followed by administration of the sequestration agent (preferably less than about 5 minutes thereafter) which captures and eliminates such toxic agents from a subject's circulation. In some embodiments, administration of a sequestration agent in temporal proximity to the CNS active agent prevents renarcotinzation and facilitates clearance of the toxic agent from the subject undergoing treatment.
100571 In some embodiments, the present disclosure provides therapeutically effective treatment of carfentanil intoxication without requiring the administration substantially higher amounts of naloxone (than required to treat fentanyl intoxication) and without requiring repeated administration of naloxone to prevent re-narcotization. Thus, the results demonstrate that (1) a sequestrant described herein (e.g., Compound A) was able to rapidly sequester and clear a toxic agent (e.g., an opioid such as Carfentanil); and that (2) a CNS active agent (e.g., naloxone) was effective at binding to the opioid receptor and displacing the toxic agent, without the need for multiple administrations.
100581 The present disclosure is related to the use of compositions that are further described below for reversal of the effects of intoxicating agents, as well as for reversal of the effects of other agents that are more fully described herein. In some embodiments, the disclosure provides embodiments that are suitable for use in reversal of drug-induced neuromuscular block, or for reversal of anesthesia, or for reversal of the effects of an intoxication by a drug of abuse, or an antidepressant or other agent. In some embodiments, the disclosure includes reversing the effect of one or more agents which include but are not limited to opioids, cocaine, heroin,

100711 Cucurbiturils molecular containers are macrocycles comprising n glycoluril monomers linked by 2n methylene groups that can be prepared by the condensation of glycoluril and formaldehyde under strongly acidic conditions. The molecular structure of cucurbiturils features a central hydrophobic cavity that is guarded by two symmetry equivalent ureidyl carbonyl portals
-15-of highly negative electrostatic potential. Thus, cucurbiturils show a preference to bind molecules that feature a central hydrophobic domain that is flanked by cationic (e.g., ammonium) groups.
Binding of molecules are mediated by the hydrophobic effects and ion-dipole interactions In some cases, ultra tight binding (Ka > 1012 M-1) has been observed in some cucurbiturils designed to bind to adamantane, diamantine, and ferrocene.
100721 Acyclic cucurbiturils molecular containers are similar but exhibit higher water solubility and can provide a more flexible binding cavity that can accommodate larger molecules. Acyclic cucurbiturils mediate tight binding through interaction of hydrophobic cations but can also be modified synthetically. These molecules feature a central glycouril tetramer to impart a C-shape and hydrophobic cation binding properties, presented by two terminal aromatic side walls to engage in cation -n-, CH-n, and TC - 71" interaction with molecules. Four sodium sulfonate arms help enhance water solubility and promote secondary electrostatic interactions between the cucurbituril and the bound molecule.

In some embodiments, the opioid receptor antagonist
-17-is a mu opioid receptor antagonist, such as naloxone or naltrexone, or pharmaceutically acceptable salts thereof. In one embodiment, the opioid receptor antagonist is naloxone, naloxone base, or a pharmaceutically acceptable salt thereof, including naloxone HC1, naloxone HCI
dihydrate, or combinations thereof. Naloxone hydrochloride is a synthetic congener of oxymorphone. In structure it differs from oxymorphone in that the methyl group on the nitrogen atom is replaced by an allyl group. It is known chemically as 17-ally1-4,5 a-epoxy, 3-14-dihydroxymorphinan-6-one hydrochloride. It has a molecular weight of 363.84, contains four chiral centers, and the following structural formula: Ci9H22C1N04.
100831 Naloxone hydrochloride occurs as a white to slightly off-white powder, and is soluble in water, in dilute acids, and in strong alkali; slightly soluble in alcohol;
practically insoluble in ether and in chloroform. Naloxone prevents or reverses the effects of opioids including respiratory depression, sedation and hypotension. Also, it can reverse the psychotomimetic and dysphoric effects of agonist-antagonists such as pentazocine. Naloxone is an essentially pure opioid receptor antagonist, i.e., it does not possess the "agonistic" or morphine-like properties characteristic of other opioid receptor antagonists. When administered in usual doses in the absence of opioids or agonistic effects of other opioid receptor antagonists, it exhibits essentially no pharmacologic activity. Naloxone has not been shown to produce tolerance or cause physical or psychological dependence. In the presence of physical dependence on opioids, naloxone will produce withdrawal symptoms. However, in the presence of opioid dependence, withdrawal symptoms will appear within minutes of naloxone administration and will subside in about 2 hours. The severity and duration of the withdrawal syndrome are related to the dose and route of administration of naloxone and to the degree and type of dependence. While the mechanism of action of naloxone is not fully understood, in vitro evidence suggests that naloxone antagonizes opioid effects by competing for the mu, kappa, and sigma opiate receptor sites in the CNS, with the greatest affinity for the mu receptor. Other opioid receptor antagonists, for example, cyclazocine and naltrexone, both of which have cyclopropylmethyl substitutions on the nitrogen, retain much of their efficacy and their durations of action are much longer, approaching 24 hours after demonstration.
100841 Naloxone has a short half-life (-60 min) and is becoming less effective against newer synthetic opioids that have a longer half-life, such as fentanyl with a half-life of 10-12 hrs. This often results in a secondary overdose phenomenon known as renarcotization.
100851 to avoid renarcotization, the standard of care is to administer higher and more frequent doses of naloxone. However, this can lead to a secondary complication called precipitated opioid withdrawal (POW), a serious and sometimes life-threatening condition.

100861 Treatment of methamphetamine intoxication or overdose with naloxone is not sufficiently effective. Thus, treatment of polydrug intoxication or overdose with naloxone may not be sufficient. Therefore, it is necessary to find other treatments that would be able to remove the drug of abuse to effectively treat polydrug intoxication or overdose.
100871 Naltrexone is another opioid receptor antagonist. However, equiantagonistic doses of other opioid receptor antagonists, including but not limited to naloxone, nalmephene, cyclazocine, and levallorphan can be utilized in accordance with the present disclosure. The ratio of such other antagonists to a particular opioid agonist can be readily determined without undue experimentation by one skilled in the art who desires to utilize a different opioid receptor antagonist than naltrexone, and the ratio of opioid antagonist to opioid agonists is exemplified and discussed in detail herein. Those skilled in the art may determine such ratios of other antagonists to opioid agonists, e.g., by conducting the same or similar clinical studies set forth in the examples appended herein. Thus, combinations of opioid receptor antagonists/opioid agonists which are orally, intravenously, sublingually, intramuscularly, or subcutaneously administered in ratios which are equivalent to the ratio of, e.g., naltrexone to hydrocodone set forth herein are considered to be within the scope of the present disclosure and within the scope of the appended claims. For example, in certain embodiments of the disclosure naloxone is utilized as the opioid receptor antagonist, the amount of naloxone included in the dosage form being large enough to provide an equiantagonistic effect as naltrexone were included in the combination.
100881 In some embodiments, naloxone (e.g., Narcan 8) is administered orally, as an injectable, or as an inhalant. In some embodiments, the opioid receptor antagonist can be Suboxone 8, naltrexone, or methylnaltrexone.

However, equiantagonistic doses of other opioid receptor antagonists, including but not limited to naloxone, nalmephene, cyclazocine, and levallorphan can be utilized in accordance with the present disclosure. The ratio of such other antagonists to a particular opioid agonist can be readily determined without undue experimentation by one skilled in the art who desires to utilize a different opioid receptor antagonist than naltrexone, and the ratio of opioid antagonist to opioid agonists is exemplified and discussed in detail herein. Those skilled in the art may determine such ratios of other antagonists to opioid agonists, e.g., by conducting the same or similar clinical studies set forth in the examples appended herein. Thus, combinations of opioid receptor antagonists/opioid agonists which are orally, intravenously, sublingually, intramuscularly, or subcutaneously administered in ratios which are equivalent to the ratio of, e.g., naltrexone to hydrocodone set forth herein are considered to be within the scope of the present disclosure and within the scope of the appended claims.

101111 The term "substance use disorder" as used in the present application refers to any stages associated with administration of, addiction to and withdrawal from a substance of abuse. This includes craving a substance, administering the substance and experiencing euphoria (a high), contentment or relaxation. When abstinent from the substance the subject may experience irritability, anxiety, sweating, nausea, vomiting, diarrhea, fatigue, tremors, headache, insomnia, loss of concentration, hallucinations, seizures and increased cravings. These are also known as withdrawal symptoms.
101121 In some embodiments, the toxic agent is an opioid. In some embodiments, the opioid can be opium, fentanyl, carfentanil, hydrocodone, codeine, morphine, or any combination thereof Overdose of opioids can be recognized through the appearance of pinpoint pupils, loss of consciousness, depressed heart rate, and difficulties breathing. Difficulty breathing results in lower oxygen levels. In addition, this can manifest in a subject as a lower respiration rate compared to an individual who does not have a opioid overdose.
10113] In some embodiments, the toxic agent is a stimulant. A stimulant is a substance that raises levels of physiological or nervous activity in the body, which, at high doses, can lead to dangerously high body temperature.; irregular heartbeat, heart failure, seizures, and death. In some embodiments, the stimulant can be caffeine, Ritalin, cocaine, amphetamines, crystal meth, methamphetamines, phencyclidine, cocaine, 3,4-methylenedioxy-methamphetamine (MDMA), and the like.

-34-EXAMPLES:
Example 1: Assessment of a combination of naloxone and a sequestration agent for the resolution of narcotic intoxication and mitigation of renarcotization 101521 African green monkeys (AGMs; n=8) were exposed to 15 lag/kg (sc) carfentanil.
Naloxone (355.12 lag/kg, im) was administered at loss of posture or < 10 breaths per minute (bpm) followed immediately with Compound A (100 or 200 mg/kg, im). A second dose of naloxone (355.12 ig/kg, im) was administered within approximately 3 minutes if respiration rate was < 10 bpm or respiration quality was declining.
101531 The average latency to naloxone administration is presented in the table below. Initial treatment with Compound A (100 mg/kg) and naloxone was sufficient in 3/8 (number responding/total number) to attenuate carfentanil-induced respiratory depression for the duration of the experiment. Respiratory rates at the end of testing were between 15 and 20 breaths per minute (bpm) for three AGMs that did not require additional naloxone at the end of testing. The remaining five AGMs required a second naloxone dose). One AGM remained apneic after the initial dose of naloxone and required a second naloxone dose that was administered within three minutes of the initial treatment. Additional naloxone beyond the second dose was not required.
The other four were ataxic with shallow erratic breaths of about or below 12 bpm. In contrast, none of the AGMs administered 200 mg/kg Compound A required an additional naloxone dose at the end of the day, and respiratory rates at the end of the day were mostly normal (16-24 bpm) with the exception of one AGM with a steady rate of 14 bpm. In the 200 mg/kg group, only one AGM failed to respond to the initial dose of naloxone and was administered another dose 3 minutes later.

101541 The majority of AGMs (6/8) administered 100 mg/kg Compound A after exposure consumed some or all of daily enrichment and/or biscuits by the end of the day. The remaining AGMs each wasted 39% of the daily biscuit allotment. Biscuit waste (22%) was evident in only one of eight AGMs when treated with 200 mg/kg Compound A. In contrast, most AGMs exposed to carfentanil and treated with naloxone show little if any interest in food.
In a previous study, four of five male AGMs exposed to 15 mg/kg carfentanil and treated with naloxone wasted >
50% of allotted biscuits.
101551 In a safety assessment, both Compound A and the combination of Compound A and naloxone were well tolerated by all study subjects.
Example 2: Dose Dependent Treatment using Compound A for fentanyl-induced respiration depression 101561 In this study, 30 rats were administered fentanyl and administered Compound A
intramuscularly approximately 12 - 15 minutes after the initiation of fentanyl infusion. At 12-15 minutes, minute ventilation (percent from pre-fentanyl baseline) was significantly lower than the base line (*: p <0.001). In the Compound A treatment dosing schemes, each dosing scheme was provided significant improvement in minute ventilation compared to the preceding lower dose of Compound A (#: p<0.001) (FIG. 2) Example 3: Evaluation of Compound A Treatment of Carfentanil and Methamphetamine Intoxication 101571 African green monkeys (AGMs) are exposed to 15 ng/kg (sc) carfentanil and methamphetamine and administered naloxone and Compound A. For example, naloxone (355.12 ng/kg, im) is administered at loss of posture or < 10 breaths per minute (bpm) and is followed immediately with Compound A (100 or 200 mg/kg, im). A second dose of naloxone (355.12 ng/kg, im) is administered within approximately 3 minutes if respiration rate is < 10 bpm or respiration quality is declining.
101581 For example, initial treatment with Compound A (100 mg/kg or 200 mg/kg) and naloxone may be sufficient to attenuate carfentanil/methamphetamine induced respiratory depression. If loss of posture or depressed respiratory rate is observed, another dose naloxone is administered.
If no loss of posture or depressed respiratory rate is observed, then no naloxone is administered to the AGM. In addition, loss of appetite is monitored to determine if appetite can be restored after treatment.

Example 2: Dose Dependent Treatment using Compound A for fentanyl-induced respiration depression 101561 In this study, 30 rats were administered fentanyl and administered Compound A
intramuscularly approximately 12 - 15 minutes after the initiation of fentanyl infusion. At 12-15 minutes, minute ventilation (percent from pre-fentanyl baseline) was significantly lower than the base line (*: p <0.001). In the Compound A treatment dosing schemes, each dosing scheme was provided significant improvement in minute ventilation compared to the preceding lower dose of Compound A (#: p<0.001) (FIG. 2) Example 3: Evaluation of Compound A Treatment of Carfentanil and Methamphetamine Intoxication 101571 African green monkeys (AGMs) are exposed to 15 ng/kg (sc) carfentanil and methamphetamine and administered naloxone and Compound A. For example, naloxone (355.12 ng/kg, im) is administered at loss of posture or < 10 breaths per minute (bpm) and is followed immediately with Compound A (100 or 200 mg/kg, im). A second dose of naloxone (355.12 ng/kg, im) is administered within approximately 3 minutes if respiration rate is < 10 bpm or respiration quality is declining.
101581 For example, initial treatment with Compound A (100 mg/kg or 200 mg/kg) and naloxone may be sufficient to attenuate carfentanil/methamphetamine induced respiratory depression. If loss of posture or depressed respiratory rate is observed, another dose naloxone is administered.
If no loss of posture or depressed respiratory rate is observed, then no naloxone is administered to the AGM. In addition, loss of appetite is monitored to determine if appetite can be restored after treatment.
-36-Example 4: Determination of renal clearance of Compound A sequestered compounds 101591 To determine the efficacy of Compound A sequestering of the tested compounds lead to reduction of a compound in the bloodstream.
101601 For example, African green monkeys (AGMs) are exposed to of different opioids, stimulants, and narcotics. Naloxone (355.12 ug/kg, im) is administered at loss of posture or < 10 breaths per minute (bpm) followed immediately with Compound A (100 or 200 mg/kg, im). A
second dose of naloxone (355.12 us/kg, im) is administered within approximately 3 minutes if respiration rate was < 10 bpm or respiration quality was declining. During the course of the treatment and after the treatment, urine is collected and analyzed to determine if an increase of Compound A-bound compounds are excreted.
Example 5: Dose Dependent Treatment using coformulation of Compound A and naloxone 101611 Sprague-Dawley rats were administered 20 mg/kg of carfentanil vi IV, immediately followed by a coformulation of Compound A (400mg/kg) and naloxone (0.5mg/kg) via WI
inj ecti on.
101621 The coformulation of Compound A and naloxone was prepared by weighing out the appropriate amount of naloxone and Compound A and dissolving in 90% of the desired volume of water for injection (WFI). Vortex for 1 minute or until a clear solution is achieved. Adjust pH
to pH 7-8 if necessary. Q.s. to final volume with WFI.
101631 The coformulation of Compound A and naloxone rapidly sequestered the carfentanil in the plasma, significantly lowering the level of carfentanil in the plasma in the rats receiving the coformulation compared to the level of carfentanil in the rats receiving the saline control.
101641 FIG. 3 shows the urine concentration of carfentanil at 120 minutes after administration of carfentanil (IV, 20 Js/kg) followed immediately by either saline control or formulation (IM, 400 mg/kg Compound A and 0.5 mg/kg naloxone). Animals treated with the formulation demonstrate a ¨5-fold increased clearance of carfentanil into urine versus saline control.
Error bars indicate maximum and minimum values for each group.
101651 In addition, the coformulation reverses Loss of Righting Reflex (LORR) in 14 minutes versus 60 minutes for saline. Further, the coformulation restores respiration in 5min. Table 5 below shows breaths per minute after 20 ug/kg carfentanil followed immediately by formulation of 400 mg/kg Compound A and 0.5 mg/kg naloxone.

[0166] Breaths per minute were calculated based on manual counting of chest contractions from high quality videos of the rats after administration of the formulation.
[0167] It should be noted that 0.5 mg/kg naloxone, converted to Human Equivalent Dose (HED) is 0.081 mg/kg or 5.6 mg for 70 kg human.
[0168] Carfentanil is a synthetic opioid approximately 10,000 times more potent than morphine and 100 times more potent than fentanyl. The estimated lethal dose of fentanyl in humans is 2 mg. A shortcoming of opioid receptor antagonists is re-narcotization after initial treatment, thereby necessitating repeat administration. Long-standing advisories from CDC
and other federal and state authorities have cautioned that multiple doses of naloxone may need to be administered per overdose event because of fentanyl's increased potency relative to other opioids.
[0169] The combination and method of the present disclosure provides therapeutically effective treatment of carfentanil intoxication without requiring the administration substantially higher amounts of naloxone (than required to treat fentanyl intoxication) and without requiring repeated administration of naloxone to prevent re-narcotization. Thus, the results demonstrate that (1) a sequestrant described herein (e.g., Compound A) was able to rapidly sequester and clear a toxic agent (e.g., an opioid such as Carfentanil); and that (2) a CNS active agent (e.g., naloxone) was effective at binding to the opioid receptor and displacing the toxic agent, without the need for multiple administrations.
[0170] The data described herein demonstrates that the described method of administering Compound A and naloxone, when administered in as Example 1 or in coformulation as in Example 5, rapidly restores respiration, reverses LORR, reduces the level of opioid in the plasma, increases the clearance of opioid into the urine, and reduces re-narcotization. This is effective across a broad range of CNS active agents and a broad range of coformulation ratios.

Example 6: Co-Formulation of Naloxone and Compound A
-38-101711 Samples of Compound A and naloxone were prepared in D20 with molar ratios of, 1:0, 0:1, 0.5:1, 0.75:1,1:1, 1:1.05, 1:1.10, 1:1.2, and 1:1.35 respectively.
Analysis of the 1H NMR.
spectra of these samples (FIG. 4) shows that Compound A is binding naloxone.
Firstly, the singlet corresponding to the aromatic protons of Compound A becomes asymmetrical when naloxone is added (spectra C, D). Additionally, several significant chemical shift changes occur.
The naloxone singlet at 6 5.09 (spectrum B) is not visible when Compound A is added (spectra C
and D) and has likely shifted upfield where it would be obscured by the water signal. Likewise, the signals from naloxone's vinyl protons (6 5.96, 5.68) are shifted after addition of Compound A indicating that binding has occurred. Further addition of Compound A, after a 1 :1 ratio of Compound A to naloxone is. reached, does not significantly change the NMR
spectra obtained, which indicates that no significant change in the binding can be observed beyond this point using NMR.
